ATTACHMENT FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 520,615, dated May 29,1894. Application filed December 26, 1893:. Serial No. 494,699- (Nomodel) To all whom it may concern.-

Be it known that I, JAMES RICE RUTHER FORD, a citizen of the UnitedStates, residing at Paris, in the county of Lamar and State of Texas,have invented certain new and useful Improvements in Attachments forLocomotives, of which the following is a full, clear, and exactdescription.

This invention relates to locomotives generally, and has for itsparticular object the construction-of a simple safety device to beattached to a locomotive to prevent train robbers or other unwelcomeintruders from getting in a position on the locomotive or tender wherethey can control the engineer.

The invention consists of the details of construction hereinafterdescribed and claimed.

In the accompanying drawings: Figure 1 represents the rear elevation ofa locomotive provided with my improved safety attachment, and Fig. 2 isa side elevation partly in section of the same.

Referring to the drawings by letter, A represents the boiler-head of thelocomotive; a, a, a the steam pipes of my apparatus; B the valvecontrolling the passage of the steam into the pipes; and C an extrawhistle so connected to the valve B that when the valve handle I) isturned to allow the passage of steam to the pipes a, a, a the whistlelever 0 will be pulled by the cord c'- and the passage of steam to theextra whistle opened, and thus the Whistle will be sounded to ap prisethe train crew of the danger.

From the boiler, at any convenient point, is led a pipe 07 to the valveB, which in the drawings is shown as an ordinary three way cook, butwhich may be provided with any number of ways according to the number ofpipes a, a, (2. provided. The pipes at, a, a may be of any numbersufficient to lead the steam to the jets at the points of ingress orentrance to the cab. As shown in the drawings, the pipes a, a, lead, onopposite sides of the cab, from the valve along the boilerhead'to thefloor at the respective sides, along the floor to the outside of theframe of the cab'and then turn downward at a point adjacent to the stepsof the cab or any other point which may appear more serviceable for thedischarge of steam at or against any intruder. The ends of the pipes a,a, may be left open to permit the outflow of steam when the valve B isopened, but I prefer to close them and make a number of small holes a inthe sides of the pipes a, a in such way as to cover, and when the valveis opened, throw a jet of steam across, the entrances to the cab.

The piped leads up from the valve B to the top of the boiler head to theinside face a for the outlet of the steam. These holes are placed towardthe under sides of the pipes a a so that the escape of steam will bedownward in such direction as to cover the tender.

The. valve B may be located in the pipe at and the pipes a, a, a joinedat a point be yond the valve, so that, when the valve is opened, steamwill be admitted to all the pipes or, a, or at once, or I may provideany other suitable form of valve. It is obvious, also, that the valvehandle I) need not be in the center of the boiler-head, but may beanywhere within convenient reach of the engineer or fireman. Noris thearrangement and size of the steam pipes a, a, a material, for they maybe of any convenient size or location or arrangement in the cab, or onits outside.

By means of proper attachments, pipes, valves and openings I may extendthe steam current to any car or place on car or train.-

Having thus described my invention, I claim- In a locomotive steamengine, the combination with the cab or housing for the engineer, ofsteam pipes connecting with the boiler and extending to the entrances ofthe cab or housing and there provided with open jets, a valve in saidpipes whereby when the occasion arises, the engineer may cause steam orhot water to be projected across said entrances to prevent the entranceof intruders, and an alarm whistle whose operating lever is connectedwith said valve, substantially as and for the purpose set forth.

In testimony whereof I subscribe my signature in presence of twowitnesses.
